Interestingly, the abdominal warts and muscular depressions appeared to fluoresce brightly under ultraviolet. It might have served as an additional attractant for unsuspecting prey!

This dung mimic crab spider does not weave any web, and relies heavily on attracting prey to it. Ambush predation is typical for spiders in the crab spider family, Thomisidae. Locally, we have been calling this the peanut dung spider because of its resemblance to sticky peanut bars.

Anterior view shows the face of the predator where the legs are more obvious while the poop illusion is less convincing.

This dung spider specializes in creating a "splatter" of silk, and sits on it, simulating the white stain caused by the bird-droppings when splashed on a leaf. This species is probably Phrynarachne decipiens or one close to it. We found this species in Borneo Bootcamp 2015, and hope to see it again in the next Bootcamp!

A distinctive species, this is probably Phrynarachne ceylonica. It doesn't really look like bird dung on its own, but the disguise is more believable when it sits on its radiating nest which looked like a bird dropping splatter.

Most dung-mimics sport a wet and lumpy surface to resemble fresh bird excrement. At rest, they draw their legs close to their bodies to conceal its shape and would lie motionless for hours in the day. This is probably the best poop-mimic, hence the title "King of Poop".

Younger specimens may come in various shades of brown. The easiest way to differentiate real poop from a spider, is that real poop would never be symmetrical while spiders should show distinct symmetry.

This shit is real. Not a spider. Just to highlight the knobbly, wet appearance of fresh poop!

This dung spider was found in Singapore, and looks superficially like the previous peanut dung spider. It lacks the extreme lumpy surface on its abdomen, but bears numerous tubercles, most notably the two posterior projections.

Another different color morph of this species.

Another piece of poop for comparison. Unfortunately I kept forgetting to take photos of the poop splatter.

Beautiful colors for a poop-mimic! Locally, some of us called this the bak-zhang (rice dumpling) spider.

Not all species of Pasilobus are as lumpy as the one described earlier. Some are smoother but there is little doubt that they are dung-mimics.
